8-BIT SOUND CHIP IN YOUR POCKET
SynthAteBit is a chiptune studio built on an authentic emulation of vintage console sound hardware. Not oscillators pretending to be a chip: two pulse channels driven by an 11-bit integer timer, a triangle channel using the hardware's 32-step sequence, and a noise channel built on a 15-bit LFSR, combined with the chip's own non-linear mixing. High notes drift very slightly out of tune, exactly as they do on real hardware.

DESCRIBE A SONG, GET A SONG
Type "upbeat heroic overworld theme" or "angry metal boss fight in D minor" and the composer writes a complete, multi-section song across all four channels. It reads mood, setting, tempo and key straight out of your words. Every song is reproducible from its seed — lock the seed to explore variations on one idea, or reroll for something new.
It runs entirely on your device. No account, no sign-in, no internet. It works in airplane mode.

THEN MAKE IT YOURS
• Piano roll — draw, drag and resize notes with your finger. The other three channels sit behind the one you are editing as ghosts, so parts line up. Pinch to zoom.
• Tracker — the same song as a classic tracker-style hex grid. Edit in either view and both update instantly.
• Instruments — volume envelopes with sustain loops, arpeggios, vibrato, pitch envelopes, and all four hardware duty cycles.
• Sound effects — jump, coin, laser, explosion, power-up, hurt and blip presets, a Mutate button, and instant playback on every change.

PLAY IT IN
Plug in a USB MIDI keyboard and play parts straight into the tracker, or record live against the playhead. Velocity curves, octave shift and transpose are all there. Your computer keyboard works as a piano too, and every key is rebindable.

EXPORT FOR YOUR GAME
Render to WAV, MP3 or OGG through the same emulator that plays it live — choosing which channels to include and how many times it loops. Or save the project file to open again later. Everything is written to your device and shared through the normal Android share sheet.
